MAX77620/MAX20024 are Power Management IC from the MAXIM.
It supports RTC, multiple GPIOs, multiple DCDC and LDOs,
watchdog, clock etc.

Add MFD drier to provides common support for accessing the
device; additional drivers is developed on respected subsystem
in order to use the functionality of the device.

This patch adds support for the Active-semi ACT8945A PMIC.
It is a Multi Function Device with the following subdevices:
 - Regulator
 - Charger

It is interfaced to the host controller using I2C interface,
ACT8945A is a child device of the I2C.

The AXP223 is a new PMIC commonly paired with Allwinner A23/A33 SoCs.
It is functionally identical to AXP221; only the regulator default
voltage/status and the external host interface are different.

The axp20x driver assumes the device is i2c based. This is not the
case with later chips, which use a proprietary 2 wire serial bus
by Allwinner called "Reduced Serial Bus".

This patch follows the example of mfd/wm831x and splits it into
an interface independent core, and an i2c specific glue layer.
MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate
symbols, allowing the driver to be built as modules.

Whitespace and other style errors in the moved i2c specific code
have been fixed. Included but unused header files are removed as
well.
